Israel is just to important strategically for us to weaken it… and division, unless done extremely carefully, would weaken it because it is just so small. (Maybe 2X the size of Riverside County, if that).
After seeing a relief picture of the Golan Heights and how thoroughly they overlook something like the northern 1/3 of Israel, I can see why the Israelis occupied them.
The original (1946) partition of Israel was a joke– indefensible Swiss cheese. And when immediately forced to defend, the Israelis fixed that pretty quick.
No surprise to me the Israelis are very, very sensitive to tactical/strategic threats to them. They just don’t have the margin of distance a Russia or US has.
